We do not have any details on plans and pricing, but hopefully the end of the Globe exclusivity agreement brings better deals. The iPhone has been really overpriced under Globe Telecom for the past few years.
Hopefully Apple also sells unlock phones through it local Apple stores. At US$649 for the 16GB iPhone 4S, we would estimate a unlocked unit to cost about Php31,000. Carrier subsidized units should hopefully be less expensive.
