The deal is quite simple get 50% off the access fee for the first 5 months on your Virgin Mobile Postpaid account, EXCLUDES APPLE PRODUCTS and BYO.
Available are a range of Samsung (Note 2 4G, SGS 2,SGS3 3G or 4G), HTC quite a few and a Sony Xperia™ acro S
The T&C of this deal also say NEW SERVICES ONLY, however existing customers should just ask when you use the upgrade number and all should be good.
In my opinion this a good deal as far as Postpaid services are concerned, also the OPTUS Network which Virgin Mobile operates on is quite reliable in my experience.
