Purchase a 2GB micro SD card

A copy of Iguidance 4

and you can have unlimited access to the US/Canada on you phone with the GPS built in, no need for a monthly fee and the software will work on any new phone you upgrade to.
I have used Iguidance on 3 windows mobile phones so far, PPC6700, IP830w and now the Mogul. The Text to speech is great and the maps are more accurate than TOMTOMs and render with more text on screen (identifying streets). Complete US/Canada maps are 1.3 GB and it fits nicely on the 2GB Microsd card. With the prices as of today you break even in 12 months vs using the spring $9.99 per month service, and do not need to be in a Sprint signal location to use the GPS capability of your phone.
Cheers.
