This is a recap of the feedback I've gotten so far. (which has been great...thanks)
First: S2U2 is great. I thought it was a little too iPhony for me with the whole 'slide to unlock' idea, but there are quite a few features and I'm really enjoying it. So thanks.
Second: I'm positive it's not the Weather Tab. But no matter what I try on Advanced Config, I can't stop it from connecting randomly (but thank you '
jimd144' for the suggestion). It must be Pocket Express (which I don't want to get rid of). But I can't stop it. The Adv Config thing will stop it if I select 'Update' on the Weather Tab and then disconnect after 10 seconds (and doesn't seem to affect my web browsing), but hasn't helped with my Pocket Express issue. Although I do have a question about the icon. As you know the data icon is two arrows moving in opposite directions above a signal meter. But I've noticed that sometimes the arrows are white, and sometimes they're gray...have I overlooked something obvious and made a fool of myself by making such a rookie mistake? I hope so. But it seems too easy.
I still have yet to try Pocket Shield but only because S2U2 really solves my problem, but I'll probably download it tonight anyway. As for an OEM case, I already have a great case. Makes the phone actually seem smaller still, but truth be told I did upgrade from a 6700.
Thanks again everyone. I am still looking for solutions for issues 1 and 3, and I hope this thread helps us all!!!
