Phone started losing wifi connections coupled with random freezes and reboots and power problems in that the phone would discharege extremely quickly.
Following call to HTC support in UK received RMA details, printed of delivery forms, packed up the phone and dropped of with UPS on a Friday afternoon, phone arrived at regeneris on Monday, no movement or update on system then phone returned following Friday.
No note in to say what was done or any email to say it was being returned!
Phone call to HTC support to find out what had been done and was informed that the Motherboard and battery had been replaced.
On a power front the phone is much better at keeping a charge and I have to report taht apart from the non existent contact Regeneris at Huntingdon seem to have done a good job and I am happy with turnaround time and the repair.....well done HTC.
