I have two "n00bish" questions, so I apologize. 1) I have a T-Mobile G2. I got this nifty T-Mobile "gel" case for it. It's actually a hard case with 2 pieces. works great. I just got another case though that's similar and it's blue. I'd like to switch them off but I can't for the life of me get the gel case off my phone. Anyone know how? 2) I see you can "move" apps to the SD card. What are the advantages of this? Do the apps actually RUN off the SD card? I haven't moved any over yet. If they actually are located and run off the SD card, it would probably save a lot of phone space, right? How does it impact the running of apps as well as battery life? I would think if the phone has to access the SD card a lot for apps, the battery would go down more. Thanks.
