Scott has an HTC One that he used at AT&T but he's had it unlocked and moved over to T-Mobile. But his MMS and text messaging aren't working now. Leo says that it may be that the APN settings are wrong, and that won't allow the phone to send images. There also may be an issue with the frequencies supported.
Todd has been having a lot of problems getting his 2009 iMac to boot with Mavericks, and he's been having problems with audio cutting out when watching videos. Leo says that Mavericks seems to have a lot of bugs, and since most of them are not consistent on every machine, it's hard for Apple to fix them. We put Apple up on a pedestal, and expect more from them, but there are bugs and problems nonetheless. Leo says that his installation sounds particularly bad, so he should try reinstalling Mavericks. If the problem persists, it could be that he has a failing hard drive.
Taylor has an iPad 3 with Verizon 4G. Despite having plenty of data left, he gets a message on the iPad saying that he's reached his data limit. Then when he clicks "later" to dismiss the message, it won't let him access data. He's called Verizon, but they are claiming it's an Apple issue.
