Here’s a rumor that seems plausible but I’m kind of cautious about reporting. Walmart is begging Apple to come and sell the iPhone at its stores. Apple might agree to this and cut a deal like it did with Best Buy. Now BGR is reporting that a new 4GB iPhone (possibly 3G) will be sold at the low price of $99 in order to attract Walmart’s customer base. Will it happen? I’m not holding my breath but it never hurts to be a believer.
