Problems Seen on Ultrasn0w v0.9

Submitted by Dan; July 19, 2009


The iPhone Dev Team released an update to ultrasn0w (Version 0.9) and the update fixed a majority of problems seen by ultrasn0w users but you may still see a few problems here and there... Problems you may see include:

• Unusual battery depletion is almost always caused by people choosing to Restore from backup instead of Setup as new iPhone when iTunes asks you. This isnt caused by either the jailbreak or the unlock, but its a common 3.0 snafu. The fix is to just re-run the official 3.0 restore and choose Setup as new this time. Your music and apps and all that will still be synced, but youll get rid of any conflicting wifi, bluetooth, or carrier settings. Then just re-run redsn0w and install ultrasn0w.
• Remember, ultrasn0w works with hacktivated phones too, but dont outsmart redsn0w into thinking you dont need hacktivation! If you dont plan on using an official sim, dont activate via iTunes with such a sim. Just keep your unofficial sim at all times and let redsn0w and ultrasn0w handle hacktivation
• T-Mobile in the USA doesnt use the 3G frequencies that the iPhones support, so turn off 3G in Settings->General->Network. (Some T-Mobile territories gracefully hand down to Edge mode, but most do not).
• Certain unofficial plans have limitations on whether you can make calls and use data at the same time. Thats not unlock-related.
• Some people have installed previous versions of ultrasn0w using non-standard techniques. While the ultrasn0w 0.9 update should have removed all previous versions of ultrasn0w, these users may have outsmarted our removal. So make sure you dont still see /usr/bin/ultrasn0w present if youre at ultrasn0w 0.9 (which doesnt have such a binary anymore).
• If you dont need or plan to update to ultrasn0w 0.9 from a previous version, you can avoid having that red badge over Cydia by removing repo666 as a Cydia source. Dont worry, you can always add it back later :) If you follow us on twitter youll be advised of any new updates anyway.
