The EVO 4G is an awesome phone — besides the short battery life — and a lot of people are ready to jump on the 4.3-inch Android superphone when it launches on this Friday. Walmart no doubt wants a piece of the action and is joining Best Buy and Radio Shack in offering the phone for $199 straight-up, no mail-in rebate required. Sure, Walmart might have a certain Luddite stigma, but an EVO 4G is an EVO 4G no matter where where it’s purchased.
