As we reported earlier this week, some of you who have recently updated your baseband to 06.15.00 to jailbreak and unlock have been facingbattery drains issues. The problem doesn’t actually come fromUltraSn0worRedSn0w, but from the hacktivation process, for those of you who have hacktivated instead of activating the phone with an official carrier.
The issue comes from iOS 4.1 and 4.2.1 which constantly look for valid push certificates, either via wifi or your data plan (Edge or 3G). This runs down you battery and may even cause your iPhone to overheat. If you didn’t hacktivate your iPhone but simply activated it with an official carrier (ie AT&T in the US), you shouldn’t have any problem.
If on the other end you did hacktivate your iPhone, you might be experiencing the battery drain issue. Fortunately, there is now a fix for it…
Sbingner explains onhis websitehow to fix this problem by tricking your iPhone and iTunes:
Step 1:Add the following repo in Cydia: http://repo.bingner.com
Step 2:Install “SAM” and “SAMPrefs” from this repo.
Step 3:Now we’re going to revert to a stock lockdownd for SAM to function. To do so, downloadRedSn0w 0.9.6b6from ourdownloads section, launch RedSn0w and select the “Deactivate” option. This will remove the normal patches made to lockdownd and let SAM take over.
Step 4:Go to Settings > SAM, then click “De-Activate iPhone”.
Step 5:Make sure iTunes is on, plug your iPhone and let iTunes activate your iPhone. If iTunes says “Invalid SIM”, you will need to manually select a carrier under Seetings > Carrier.
At this point, you mayunlock using UltraSn0wif necessary (see ourUltraSn0w tutorialhere).
This fix will allow you to get the full benefit of push applications while increasing your battery life substantially.
