xv6700 drops calls

[turbochris]

My XV6700 recently started to drop calls for no reason. Sometimes it will drop after 2 minutes sometimes it will work fine. it's getting worse. it dropped a call today after 30 seconds, then it was unresponsive for about 10 seconds and after it started working again it dropped the call after about a minute. I think I've had it with this phone, anyone recommend a good replacement that can tether, run wm6 and have bluetooth and wifi?

Thanks
Chris
