ciwrl developers:

For those of you who are going to sit and wonder if your device will make the cut, here are two general requirements that must be satisfied:

1) Phone must have more than 256mb RAM

2) Phone must contain a decent gpu

Now, if your phone doesnt meet those, its not to say you will never get ICS; but it does mean your device will not be one of the first with CM9 (and your wait will likely be much much longer, if ever)

Here now is the list i include the phone that wont get update based on specs is.

FYI if you want to buy phones if you live in USA avoid buying Metro PCS phones,Virgin and Boost mobile. Because, their phones 85% of them wont get the next update because their ram are from 192 ram with internal storage from 75 to 125 mb like Google g1 specs from 2008 but more internal. Meaning you wont get an update because cyanogenmod wont support specs like this anymore.

Buy T-mobile,Sprint,Verizon and A&tt Phones with at least 512 MB of RAM and in my opinion internal storages of at least 400 mb and up.
