Nu ar trebui sa ai probleme, dar daca vezi ca o ia razna iPhone 3G sau 3GS-ul tau, atunci urmeaza sfaturile DevTeam
Unusual battery depletion is almost always caused by people choosing to Ã¢â‚¬Å“Restore from backupÃ¢â‚¬Â instead of Ã¢â‚¬Å“Setup as new iPhoneÃ¢â‚¬Â when iTunes asks you. This isnÃ¢â‚¬â„¢t caused by either the jailbreak or the unlock, but itÃ¢â‚¬â„¢s a common 3.0 snafu. The fix is to just re-run the official 3.0 restore and choose Ã¢â‚¬Å“Setup as newÃ¢â‚¬Â this time. Your music and apps and all that will still be synced, but youÃ¢â‚¬â„¢ll 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 donÃ¢â‚¬â„¢t outsmart redsn0w into thinking you donÃ¢â‚¬â„¢t need hacktivation! If you donÃ¢â‚¬â„¢t plan on using an official sim, donÃ¢â‚¬â„¢t 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 doesnÃ¢â‚¬â„¢t 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. ThatÃ¢â‚¬â„¢s 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 donÃ¢â‚¬â„¢t still see /usr/bin/ultrasn0w present if youÃ¢â‚¬â„¢re at ultrasn0w 0.9 (which doesnÃ¢â‚¬â„¢t have such a binary anymore).
If you donÃ¢â‚¬â„¢t 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. DonÃ¢â‚¬â„¢t worry, you can always add it back later :) If you follow us on twitter youÃ¢â‚¬â„¢ll be advised of any new updates anyway.
