I bought an HTC TP2 with mightyrom already installed (Jan. 20, 2010). I have already turned my phone on through cricket and got everything working. My phone runs pretty sluggish. So I checked out the site and found the update. I just have couple of questions. If I update, will my phone still work on the cricket network? Or will I have to have cricket set up my phone again? Please advise. Thank you for your support.
