I have an 3g iphone running 4.0 firmware. I unlocked it so I can use it withmy tmobile sim card. For tmobile I used a blackberry curve 8520 so I have a data plan and on my curve i was able to send and receive email, use the web without wifi and so forth. Can I setup my email on my iphone so that I don't neeed to use wifi to physically go to my email address and login in. I want it setup like my curve where you type in all your info and your emails come to you just like text messages. I tried to set it up myself and i couldnt get it going so im not sure if it doesnt work because i did something wrong or if that feature doesnt work at all with unlocked jailbroken iphones. alsoo if I can get it to work or even if i cant would there be any point in keeping my data plan or will it basically become obsolete because It won't run on the jailbroken iphone
