Inaccurate GPS on ipad 2?
I have an iPad 2 w/ 3G that has a consistently accurate GPS. It always seems to be off by a 1/2 mile or so.THis occurs when the wifi is turned off and the ipad is relying on the SIM card and internal GPS.
Any thoughts of what would cause the problem?

Halifax, Nova Scotia. It's definitely the device as my i phone is perfectly accurate. The iPad is always off by a half mile distance in comparison though.

Well, you are up there near the pole ;-} Even still if your iPhone is showing an accurate location I would say your iPad needs repair. Sadly, it sounds like the logic board has a problem. Was it damaged at one point (dropped or had gotten wet)? Was it serviced by someone?

It's one I've fixed up. I've replaced the digitizer, power /volume flex and wifi antenna and straightened out the frame around the dock connector.
No signs of any other issues with the logic board though. Everything else seems OK. Wonder if a system wipe & restore would help?

Can't hurt to do a wipe & restore. I think this is a timing issue within the cellular chip were the GPS signals are processed. Here's a good write up: How Global Positioning Systems Work.
