Skafia has made an awesome post on our forums about changing the carrier logo (upper left hand corner of the iPhone). and some more instructions: ----------------------------- ** To change the logo, or change your ringtones, or anything in the future, you have to "jailbreak" your iphone using the iphone hack found here: http://cre.ations.net/blog/post/custom-ringtones --sounds-on-your-iphone-using-windows Then, to change your carrier logo, just Plug in your iPhone (after it's be "jailbreaked"), close iTunes and make sure you have 2 65x20 .png files in your c:/phonedmg directory on your computer. The first logo is the one you see on the homescreen, case sensitive: FSO_CARRIER_ATT.png The second logo is the one you see everywhere else in your apps: Default_CARRIER_ATT.png Make sure they are transparent so they look nice in the toolbars of Safari and stuff. Then you just run "iphoneinterface.exe" and once it connects, do the following commands: ** EVERYTHING IS CASE SENSITIVE ** mkdir /System/Library/CoreServices/SpringBoard.app/ cd /System/Library/CoreServices/SpringBoard.app/ then type: putfile /System/Library/CoreServices/SpringBoard.app/Default_CARRIER_ATT.png then: putfile /System/Library/CoreServices/SpringBoard.app/FSO_CARRIER_ATT.png Turn your phone off, unplug it from your computer, then turn it back on.

While the pre-release build of iPhone OS 2.0, officially available only to select developers and beta testers, is sluggish and buggy overall, one area of operation has seen a dramatic performance boost. The new version of Safari included with iPhone OS 2.0 is up to 35 percent faster at executing JavaScript than previous editions of the iPhone OS. Prior testing of iPhone OS 1.x’s JavaScript performance using Celtic Kane’s benchmarks revealed performance 30 times slower than that of a 1.83 GHz MacBook Pro, with iPhone-generated test times in excess of 9000 ms on average. Under iPhone OS 2.0, however, Celtic Kane’s benchmarks run the gamut in just over 6000 ms. The iPhone OS 2.0 beta uses an updated version of WebKit — build 525.15 — to render pages in Safari.

One of the more maddening iPhone troubleshooting issues is one in which the unit suddenly resets in the middle of operation, displaying the silver Apple logo and returning the user to the home screen, interrupting any activities that were taking place. This issue is most likely to occur when the iPod function is playing music, but can also occur when browsing in Safari and performing other operations. Some recent reports from Apple’s Discussion boards:

• “The new phone randomly resets itself. I’ll be in the middle of a text or browsing a page and the screen goes black and I see the apple logo. Then the phone powers on and works fine for hours or days, then it’ll happen again totally random time.” — jwilkinson1977
• “Mine has been doing the same thing. I have replaced the SIM card, restored it, brought it to the Apple store tech folks, restored again and same thing. It happens in all applications that I am using.” — Aileen Oregon
• “My iphone will randomly reset itself and show the apple logo followed by the typical boot up. It seems to happen most often when a song finishes playing in the ipod.” — djsteev

One workaround for this issue, though somewhat tedious, is to force quit other applications before using the application that frequently triggers resets. This can be accomplished by holding down the home screen button for several seconds while in the application that you want to force quit. For instance, if you are experiencing this issue while using the iPod function, first launch Safari and force-quit it, then launch the iPod application and check for persistence of the issue. Also, if you notice that the iPod function repeatedy exhibits his behavior when accessing a certain track or piece of media, try tempoarily removing the offending item and check for persistence of the issue. Other potential workarounds from our special report on troubleshooting iPhone application crashes are as follows:

• Safari-specific: clear cache, cookies, history Try these options first if you are seeing repeated crashes in Safari. Safari for the iPhone doesn’t have a very aggressive caching mechanism, but sometimes clearing it can trigger stubborn pages to load. Cookies can also become problematic. Delete them and re-try loading the page(s). Finally, deleting History can be effective on the Desktop versions of Safari, and may also be so on the iPhone. All of these items can be cleared by using the Settings application then tapping Safari.
• Full reboot Perform a hard reboot of your iPhone as follows: Turn the iPhone off completely, by pressing and holding the Sleep/Wake button (on top of the device) for a few seconds then slide the red slider. Turn it back on by holding the Sleep/Wake button until the Apple logo appears. This can clear potentially problematic data, preventing some crash-types.
• Keep adequate free space on the iPhone’s internal memory Like its desktop relative Mac OS X, the iPhone’s OS X operating system needs some head-room on the internal flash memory in order to operate properly. Try keeping at least 10% of the total space free to potentially prevent some crashes in applications, freezes and other problems.
• Restore the iPhone Try performing a restore of your iPhone. Connect it to your Mac or PC and, in iTunes, click the Restore button under the Summary tab. Restoring the phone will erase contacts, calendars, photos and other data on the phone, but will restore automatically backed-up information including text messages, notes, call history, contact favorites, sound settings, widget settings, etc.
• Erase all content and settings As a last resort, go to the Settings application, tap General then select the Erase All Content and Settings. This will delete all media and data on the iPhone, as well as recent calls, etc., and all other settings. If you perform this operation and stop experiencing crashes, you might have problematic data being synchronized to the iPhone that is automatically put back when the phone is restored. In this case, you might want to go to iTunes, select Preferences from the File menu, then iPhone and delete your backed up iPhone settings. This includes text messages, notes, call history, contact favorites, sound settings, widget settings. Again, one or more of these data might be problematic.

BGR is claiming iPhone firmware 2.0 will provide a YouTube plugin for MobileSafari.app. They aren’t citing their source, but they’re pretty confident in their assertion:

“You heard it here first, people! The latest version of the iPhone 2.0 firmware that was just seeded to developers has a YouTube plugin for MobileSafari.app”

BGR tends to be a solid source, but we cannot confirm this to be true without some more evidence. Nonetheless, if true, YouTube video playback from within Safari will be possible on the iPhone, without launching a separate application for the content. That sure would make surfing the web and viewing content a helluva lot easier; here’s hoping BGR is bang on with this one. Boy Genius also goes onto suggest that this may be indicative of some form of native Flash support, but we just can’t raise your hopes like that. It wouldn’t be right.

The folks at Mozilla are still fuming mad over Safari-gate. The developers behind the popular open source browser Firefox stated flatly that no efforts will be made to port Firefox to iPhone, blaming Apple’s Gestapo-like restrictive software license. So this means I can’t look forward to a browser that consumes half my memory and grinds
