Why after the AT & T, most of the operators are willing to be the sole distributors of iphone and even sponsor the iphone for the end-users

According to iSuppli research, the iphone use spend around USD90 monthly for their iphone online. And the non-iphone user spend around USD57.00 only. So, AT & T earn even more even they sponsor USD200 per user in buying the iphone. The revenue is from (90- 57) x 24 = 792USD. 792 - 200 = USD592. AT & T earn USD592 per user after sold the iphone for them. So, it clearly show to all operator in the world that the iphone users would allow them to increase their ARPU.

For the commercial traveling users, they spend even more on using the mobile phone email during roaming. And it brings much more revenue for the operator. Since more than half of such travelers are not the technical guy, they do not know how to switch off temporarily for the push mail function and it keeps of IN/OUT email. For 1 - 2 weeks using, it can easily spend for USD400 - USD500 for only push mail.

AT & T willing to do it due to they earned the experience from Motorola Razr before. They took the same way of sponsor the Razr users, and it pushed the sales for double of selling the Razr before on 2005. They clone the same strategy on iphone and gain more.

In that way, we can also see that why Blackberry get welcome a lot from the operator, since the user would spend even more on ARPU than the iphone.
