Recently, a significant growth in programming for mobile devices can be observed on the IT market, especially, it is well seen in application development for iPhones. According to the data of Gartner’s 2009 report on smartphone market, the highest sales growth rate is displayed by devices with MAC OS X operating system (iPhones) – 245.7%. Then come Research In Motion (BlackBerry) and Palm OS with 96.7% and 42.2% respectively.
Lately, access to Internet services and websites is often executed via smartphones with iPhone being the leader in this segment. Owners of this device use GPRS for Internet access 30 times more often than users of other mobile phones. This is encouraged by the Apple’s concept of “always-on” Internet access when a phone uses any possible channels of access, from local Wi-Fi to global 3G, while ensuring transparent switching between them.
