Just updated my 'normal' n95 to the latest firmware.. GPS is now top notch and get full locks on multiple sattelites indoors !! even having it next to the gearstick in the car it works great and never lost the signal once.
Junk the standard maps and get the new one from smart2go !
You know in the mobile phone world the n95 is a big joke as its badly made and the software in it is s**te
