Yesterday morning my 4G was cutting in and out and no 3G at all. it would not hold a connection. i tried the usual; pull the battery, take out and replace the sim card, hard rest to no avail. i did this all with the c.s. rep on the phone. nothing worked so i had to take it in to the store and they replaced the sim card and reactivated the phone. it seemed to work fine all day but when i woke up this morning it was up to it's same old tricks.

has anyone else has had this problem?

it looks like i'm back to the store this morning.

in the mean time i used an app called phoneinfo by sc@taiwan. i was able to put the phone in 3g only.
