I purchased an E770 (well, two actually) from Vodafone a while ago and have been plagued with a very annoying problem (and a couple of slightly annoying ones).

The very annoying one is contact corruption, or something. Various entries in my contacts (I've only added about 30 so far) become corrupt in some way. When they are affected, they can not be viewed, called, edited. I cannot read any text messages from them, if they are in my call log then the call log cannot be viewed. If I dial the number manually it will not work. Not will texting to it manually.

The only solution I have found is to delete the affected entry, then I can dial it manually. However as I can't view it, I need to know the number to do so. This corrupted status seems to be transient - it happens at random to some entries, that will later be fine again. But restarting the phone, even removing the battery, has no effect.

So far this has caused me serious problems - I recently added a very important client to my contacts, only to need to call her a couple of hours later on urgent business. However my phone refused. Eventually I found another way to contact her, but this was a serious problem.

I can find very little info on the E770, it is clear that it is a Vodafone-exclusive model worldwide, and has only been in the market for a few months. I have seen reports of other phones doing this, and my second handset (my partners) has also suffered from the same problem (although she uses hers less so it isn't such a huge problem for her)

Firstly, does anyone here have a Motorola E770? And secondly, have they experienced anything similar?

Vodafone inform me that I must return it for service, three times, before I can look at getting a replacement. I am planning to return it once, and if the problem continues I will be demanding another phone.
