can work, right now i am also using this method, but a bit different.... i use a MIFI (huawei e585) using a celcom broadband plan.  phone is also on celcom heheh

may seem weird why i dont just combine, but i want to also be able to share with my netbook without finishing the battery on my phone and also because the data plan i got was only rm50

and no YES coverage here if not i would go for that one
