My girlfriend got one of these phones last week and part of the reason we chose it was because of 'signal boost' feature as we live in a bit of a rubbish area for phone signal. For the first few days this worked fine but just recently the little green house symbol that signified that it was in use always seems to be red now and not working. Anyone have a similar experience? We tried the phone at her mum's yesterday through her broadband and it remained red also so that would seem to suggest it's the phone and not our Internet. This is the first Android/HTC phone either of us have used so any help would be much appreciated.
