Last Sunday I received a message from T-Mobile, said firmware update (2.3.4) is available for my HTC myTouch 4G. After upgrade, everything looks like normal, works good. But this morning (15-Aug-2011), after I get up, I noticed I was not able to get any download to the phone. I can see the 4G icon on the top of the phone, but only upload arrow shows, the download arrows shows nothing, the tells me nothing been able to download to my phone. If I turned WiFi on, the phone start update web contents, for example, but not from 4G network, and this happened only after I had 2.3.4 installed on the myTouch 4G, never happened on 2.2.1. So I am wondering anyone has similar issue as me? and What the fix? Thanks.
