Hi I have had the HTC desire for 2 months and it is a Telstra branded phone that was purchased outright so is therefore unlocked. My carrier is Optus. I was able to set up internet and mms using the HTC dream manual. I was stoked to find an inbuilt ringtone editor that i could cut mp3 files to use as ringtones.... however now I have the issue that those ringtones no longer work and I have changed the generic ringtones back to the htcs provided ringtone, but my friends which I have allocated tones from the editor I can no longer access their details from the people widget.... also occasionally the personalise screen will freeze and force close now.... has anyone else had an issue such as this....also I can't take photos with my camera anymore and photos I had taken with camera previously have disappeared from my phone.... please help with ideas or suggestions? Would really appreciate it!
