has its fancy little iPhone 3G, but it'll be Wally World offering up the G1 outside of official T-Mobile outlets. As we'd heard yesterday, 550 Walmart stores across the country will begin selling the Android-powered handset beginning tomorrow, and folks who opt to pick one up here versus a traditional T-Mob store will save $31.11. Yep -- according to company spokeswoman Melissa O'Brien, the new / upgrade-eligible customer price for a Walmart-sourced G1 will be just $148.88 with a 2-year agreement. Wait, what? You already purchased your G1 at the full price? They always said the early bird pays the premium... or something along those lines.
