GPS not working properly

[#1]

Hi...

Up until Sunday, my Sat Nav on either Co Pilot or Google Navigation was perfect - it knew exactly where I was and was incredibly accurate.

On Sunday, for some reason, both sat nav apps can't seem to pin point my location and think I'm up to 30 feet away from where I actually am.. which then has a problem with navigation as it thinks I'm on another street.

I tried re-installing the phone software (using PC Companion, so it was completely a clean install) and this still hasn't helped.

Can anyone help me?

my x10 is rooted and my GPS is accurate enough to spot when we move from one room to aother in our house - it claims accuracy to 6 metres but I think three or four is more realistic.

Here's an interesting test for you.....

Hold your phone at arms length and make figure of eight movements with it - as large as you can and keep your arm straight.

Now check your GPS co-ordinates - I bet they have changed and they are now more accurate

but the most big problem is that my mb can't even find any of satelites, thats the main problem. it may be problem of region maybe, i am from Georgia, Tbilisi.
