AT&T wireless service, for which we pay $59 per month, is pathetic in Warsaw Missouri. Lately the service is terrible almost everywhere. iPhone (or, more specifically, iPhone users) are strangling the AT&T network. It’s not a pretty picture for AT&T. AT&T must know what their customers think of their network. If AT&T customers are telling me their tales or woe, they’re telling AT&T. If I were handcuffed to a two-year contract where I was paying big bucks (you can easily end up paying AT&T $150 a month), I’d be pretty emotional if I found out I was lumbered with the appalling levels of service that some folks seem to endure. We started with Cingular wireless and the service was great everywhere in the country. Even back in the old analog phone days (yes, we've been with them quite a while) [+]

AT&T had no part in the decision to remove Google's Google Voice iPhone application from the Apple iPhone App Store, according to a 16-page letter the telco sent to the FCC. AT&T maintains that while it has an agreement with Apple to restrict voice applications that leverage wireless networks operated by AT&T, it retains no control or review privilege for any iPhone application and Apple alone acted to remove the application. In addition, AT&T said the agreement limiting VoIP applications did not extend to VoIP apps that leverage the iPhone's WiFi capabilities. In the letter AT&T specifically mentions that part of the initial iPhone exclusivity contract required Apple to block VoIP calling functionality on the iPhone in order to protect AT&T's monthly service revenues. AT&T said in the letter that it would take a fresh look at allowing VoIP over its 3G [+]

Skype will officially pull the wraps off its Apple iPhone application Tuesday, but it seems like every reporter with an iPhone got a look at the application over the weekend. Users will be able to Skype-inate over WiFi, including free calls to other Skype users and the whole cheaper calls bit via SkypeOut. A Skype version for the BlackBerry will appear in May. PC World says that users won't be able to place calls over a cellular data network; this is a protective sop thrown to the carriers so the app won't (supposedly) diminish long-distance and roaming minutes. Presence and IM work the same and go over whatever data network is available; cellular or WiFi. Skype for iPhone will use phone numbers directly from the iPhone's address book and will also helpfully display Skype contact photos. Conference calling is available, but [+]
