Alright alright... I'll keep it on the 800w.
Me actually HAVING the phone and using the GPS instead of having some other phone, the fact is that I've never had to soft/hard reset my phone after using the GPS, an issue that I've heard the Touch Pro and some Moguls, both by HTC, have experienced. Sprint Navigation works flawlessly and so does iGuidance and Google Maps, and the GPS lock is pretty fast, even indoors. The ONLY gripe I have with it, and it's not even about the GPS itself because that works great, it's about the location search today plug-in. Results aren't sorted by distance which seems a bit strange. Other than that I'm very pleased to have a portable GPS right in my pocket
