Hi everyone ! I'm new to this forum and this is my first post. Walking around this forum a little, I feel I should have been here earlier. Here, in Chennai, aircel has a plan exclusively for iphone4. 1.5 GB of data usage(3G) for the first three months and then onwards 500MB for 297Rs. Its a great deal for the first 3 months. What I want to know is, if I get this service activated in an iphone4, can I use the same sim in my ipad? If this is not possible in the normal case, is there a workaround? Secondly, in general case, how to use 3G for ipad2 ? Would the seem need to be configured first by inserting in a mobile? Hope someone helps..
