Despite all the coverage<\/a> that Apple’s new iPhone is getting, there is still innovation going on at other cellular providers. Last week, T-Mobile announced their new “HotSpot @Home”<\/a> service. For an additional $10 a month, you can use your WiFi-equipped cellphone as a VoIP device. When you’re in range of a WiFi access point, the cellphone will use the Internet to make VoIP calls (instead of the cellular system) – and the minutes used here won’t<\/em> count towards your monthly plan, giving you essentially unlimited usage time when you make calls this way. Your phone still retains all its original functionality, such as call hold and caller ID, so your phone isn’t crippled. <\/p>\n The best part, however, is the seamless integration. As you move out of range of a hotspot, the phone will automatically hand off to T-Mobile’s cellular network, in much the same way as hand off occurs between adjacent cellphone towers when you’re moving. This is not only beneficial, but a prime example of the convergence<\/em> of wireless networks that many people believe is going to play a bigger and bigger role in the future. Kudos to T-Mobile for offering innovation in this area, instead of just a new phone with a lot of fancy features. When the iPhone was announced, the hype was almost immediate. For the most part, it’s lived up to its expectations<\/a>, but two issues identified before launch seem to have no resolution. Firstly, it can only be used with AT&T. Secondly, and perhaps more importantly, was the lack of an SDK<\/a> for the iPhone. Many people lamented this decision<\/a>, and wondered if Safari and web-apps would be able to replace the flexibility offered by a true SDK. Despite worries of data usage costs<\/a> (for the eventual non-US users), there have already been a plethora<\/a> of iPhone apps released. <\/p>\n The real reason, some say, for the lack of an SDK is perhaps Apple’s (and AT&T\/Cingular’s) worry about a VoIP application being developed for the iPhone that has the potential to severely cut into their income. After all, phone calls over the Internet wouldn’t count as regular minutes. Additionally, AT&T is known to harbour fears<\/a> of companies that “use their” pipes, especially when they’re offering services that could cut into their bottom line. The result of this is a stifling of innovation.<\/p>\n
