Likely in response to the launch of the HTC Hero on Sprint, Walmart has just dropped the price of the original Android phones. Both the T-Mobile G1 and the myTouch 3G received price drops and if you're a current T-Mobile customer wanting to get a taste of Android, it's as good a deal as you're going to find. The T-Mobile G1 is now $48.88 and the myTouch 3G is $98.88 (with new 2-year contract). It's a really great deal considering how many 'dumbphones' are offered for the same price.
Though the website still lists the T-Mobile G1 as 97.77, it looks like Tmonews has received confirmation of the price drops. We suggest you contact your local Walmart to see if they are carrying this low, low price.
