hi just wondered if anyone else has experienced this problem got my iphone 4s 2 weeks tuesday coming & ive already had to top up my data which i did last sunday but ive had 2 iphone contracts in the past & never had this problem but since having the 4s i have ive never got to 80% before i was on 750 before but now on 500 but ive had 1gb this month & its not even 2 weeks into the contract & already on 60% could this be anything to do with settings ? , when im at home im using wifi
Wish this had a more powerful processor and a bigger screen 4.5ish. You really can't tell the difference between the previous iPhone and this one.

Anonymous, 03 Nov 2011No, you cannot. It is only posible if you activated the iPhone 4S as a CDMA phone. In Singapor... morei need a phone that can be contracted to a cdma system as well as gsm system....usa-mexico can i do this with the 4s phone. i see that it has a gsm chip allso?

Anonymous, 03 Nov 2011So you can use it on both systemsIf I am not mistaken, if you buy your iPhone 4S on a CDMA network, you are also able to use it on GSM.
The part I am not so sure about, is if you buy iPhone 4S on a GSM network, can you use it on a CDMA network. So far, in this second scenario the answer is no. I may be wrong of course, but I looked around a lot for this answer.
Again, this is not because of Apple, but CDMA networks, which are more strict about phones on their network.
Anonymous, 03 Nov 2011Yes you can No, you cannot. It is only posible if you activated the iPhone 4S as a CDMA phone. In Singapore it is activated as a GSM phone.
From Apple http://www.apple.com/iphone/compare-iphones/
CDMA available only if iPhone 4S is sold and activated for use on a CDMA network.
However, an iPhone 4S activated as a CDMA on the other hand, will be able to roam using the GSM networks using sim cards.
This limitation, as I said, is nothing to do with Apple, but it is to do with how CDMA operators operate.
