PM me an email address or whatever means you want me to send you the HTCDialer.apk.
I went into my phone using "App Master", and found :
I'm assuming that when i send you this .apk (which is completely stock, from the phone described @ "/showthread.php?t=2624310"),
that you can open it on your device, and install it like any other .apk from the GooglePlay Store? Hey it's worth a shot right? Anyway, where do you want me to send you dialer.apk?
