hi there im new to this site, only got my gt540 last week. Have to first say though i love my phone! my girlfriend has a vivaz and its crap compared to the optimus! which is a third of the price! anyway the reason for the post... basicaly my gps is not working, ive tried it with several different navigation apps. it searches for a satelite and just dosent find anything? ive satin my garden for hours trying to get it working in an open sky, ive tried it at a friends in his car still nothing. Yet my brothers works straight away on his n97 any advice would be appreciated thanks!
