Hi i do not get 3G in my area. When i am connected to WIFI and my phone is locked i believe it automatically switches to the edge network. the main problem is that i do not get my emails fetched every 15 minutes for some reason. when i unlock my phone, it will show the edge icon and then switch to wifi. only after that will it tell me if i have new emails. is this normal, or is something wrong with my phone? thanks in advance!
