This user reported about a lost data connection on the iPhone which makes the GPS useless, especially when you are one hour away from home and don’t have a clue where you are heading:

I’ve had my iphone for about 4 months now. While there are many things I really dislike about the iphone, I’ve kept quiet since the pros have outweighed the cons. Not until today… After driving for about an hour going to an address I bookmarked in the GPS, my phone decided to drop signal. About 5 mins later it recovered signal, but without a data connection. GPS on the iphone is worthless without a data connection. So I decided to reboot the phone in hopes of getting the data connection back. Upon reboot, the phone decided I was no longer authorized to use it and needed to re-link via itunes.. f**king itunes… I’m an hour away from home without the address I’m going to and without the ability to make a phone call - except to 911. So what now? See if I have any quarters and look for a payphone? Never needed to do that over 3+ years using a smartphone.

Do I now need to keep a back-up phone in case the iphone decides to re-lock itself again? WTF. Apple needs to get their act together. Unfortunately, the buzz around the iphone is so big, I think they will continue to get away with unnecessarily crippled hardware and shoddy firmware. Before I purchased my iphone, I thought Apple had a reputation of having rock solid operating systems and being more open-minded than MS. Their geniuses at marketing, no doubt. Fooled me. Truth is Microsoft’s Windows Mobile OS is way more solid and they don’t purposely crippled hardware all in the name of DRM and whatever other reasons…

Having a cell phone lock itself up for no reason is 100% unacceptable. I am now one seriously po’ed Apple customer.

As always this complaint was submitted through the iPhone complaint form.
