If the phone is that critical to you, I recommend that you return it and get a regular phone. The freezing may be a hardware issue. If it is, exchanging it will correct the problem. But these phones are little computers. Even if Win 6.1 were flawless (and it is not), software applications that are installed rarely are flawless. An installed application may cause no problems for weeks, but under the right circumstances it can crash Win 6.1 or unexpectedly drain the battery. I would not call that a flaw, but the nature of the beast. Even NASA has computers crash or malfunction from time to time.

So if the phone is absolutely critical at all times, get a phone that is not dependent upon a complex operating system or that can be compromised by applications that you install. Or, like NASA, build in redundancy and get a second phone.
