i don't know whether this question have been asked here b4...or it should be asked in different topic...

let's say i'm a current maxis iphone 3gs user on ivalue1...which mean Free local calls 333 min, 100 Free sms (Maxis to Maxis only), 10 free mms (Maxis to Maxis only), & 500MB Data...and let say another 12 months to finish my contract...

when iphone4 come out with new rateplan...which is ivalue1 --> Free local calls 333 min, 200 Free sms (Maxis to Maxis only), 20 free mms (Maxis to Maxis only), & 1GB Data....will my current plan change to new one also? (extra 100 free SMS, extra 10 MMS & extra 500MB) since paying monthly same at RM100...
