Contract upgrade allows existing customers on a contract to purchase a new iPhone while retaining their existing mobile number. If you are currently under a phone contract with Maxis (iPhone and selected smartphones), then you are eligible for a contract upgrade*. A contract upgrade extends your current contract for either 12 or 24 months depending on how many months is left on your existing contract. For instance, if you are on a 12 months contract with 6 months remaining, you can purchase an iPhone 4 by extending the months on your current contract. Your new contract duration will be a total of your remaining months + the new contract upgrade period. E.g. 6 months (remaining contract) + 12 months (new contract upgrade) = 18 months (new contract period) *Terms and conditions apply.         Terms & Conditions   Apple, the Apple logo, iPhone, and Multi-Touch are trademarks of Apple Inc.
