iPhone : All are not good

We all agree that Apple's iPhone gave us a new choice in the mobile phone market. Available features in iPhone is uncomparable in today's market. But there are some features which need to be improved in this phone.

• iPhone's main drawbacks is relatively slow data network
• iPhone running on closed OS X platform. That means we have to istall softwares which are available by provider .
• Currently iPhone is exclusive to the Cingular network. Apple not releasing phone for other mobile service provider.
  
• Even though this has los of new features, $500 price tag is too high.
