I just bought mine on 15th Sept. A Desire and Wildfire from Maxis Sunway Pyramid (as they have black Wildfire in stock).

Maxis info on the purchasing is a bit mixed up. Called 123, they said you can only buy the phone with contact and the phones can attach to current data plan that I have.

Went to Maxis TTDI and Sunway, they said otherwise. You can buy the phones without the plans and in my case I cannot use my existing plan coz mine is the old data plan (Maxis unlimited).

If you lazy to do legworks, then call 123 ask them to find the stock but it gonna take 24 hours and first come first serve. Else, run around. Currently all retailers have no more stock on SIS unit, AP still can find.
