Hello everybody.. I am using a factory unlocked 3GS from Italy... Forget about all the small text below, no longer relevant. the issue I have is that i currently do not have a data plan, and need to disable all data. I was doing this by using a Fake APN profile there are tons around, however there is a problem with extremely fast battery drain if you do so. The link is for jailbroken phones but still valid explanation. http://thebigboss.org/2009/07/27/how-to-disable-edge-maybe-on-30/ Has anyone found a workaround to disable data without changing the APN this way, meaning battery drain? Used to use it with "du" in the UAE with normal iPhone battery life. Then came to Germany and I noticed it drained much faster with a local T-Mobile SIM. At first I thought it was 3.0.1 or another issue, restarted, restored etc, but before I could test and do more extensive troubleshooting I went to Italy for couple of days where I experienced much longer battery life again (Roaming on the T-Mobile SIM) Came back yesterday and the phone drains battery like crazy again I have a profile running that disables cellular data (no data plan on the German SIM), 3G is off, reception average. So all in all I feel like it is somehow connected to my carrier, or rather the local network. How can that be? Any ideas? It's frustrating.. Edit1: I found something interesting. The iPhone reports constant usage even when in standby just lying on the table. After full recharge, disconnect and then just leaving it I had 21min usage, 21min standby without touching it. I switched to Airplane mode.. and the problem disappeared. There must be something that tries to connect to the network constantly. Edit2: After some testing, it is definetly PUSH that is the culprit.. guess what, I only have MobileMe. So it seems that MobileMe tries to access Data, but since I have the wrong APN profile installed to disable Data, it does so constantly without success, generating usage and battery drain. Now I could just turn off Push but I actually would like to have it when I am in WiFi areas... Any ideas on this? I need to disable cellular data but appearantly if I do it via a fake APN profile, MobileMe goes crazy and drains my battery To sum it up, the problem is the combination of MobileMe push and the fake APN to disable data. Any workaround appreciated. Edit 3: It is not push/fetch/MobileMe. It seems to be the Data disabler.. from unlockit.co.nz. Will drop those guys an E-Mail, has anyone else experienced this? Please help..
