my htc hero (build no 220.127.116.11) on orange, keeps dropping in mid conversation even when there appears to be signal, although i have to say most of the time it is terrible at keeping signal .. other phones with same sim work fine. It will also not download or send picture messages very often, and i sturggle again to find reception to send text messages. This phone is a nitemare, it seems fully capable of doing all the trick stuff but cannto function as its primary intention ... a phone! This is so frustrating, i woudl honestly go back to nokia on o2 if i didnt have a 1.5yr contract with orange. If there is any way to solve these problems that anyone knows of its greatly appreciate it ta.
