Why I will never use any Lumia in work or priv? Lumia is exposed with Windows Phone bug, which allows to disable any software on any WP device, Lumia 800 in this number and all the others. The particular string of characters, when displayed, causes Windows Phone to restart, and after restart the application which has processed this secret string stops running, even after several attempts to reboot. Hence a hard reset by an authorised service centre is the only solution. The proper character combination triggers the problem when it is displayed in any application which includes a danger of receiving (and subsequently processing) it via SMS, MMS, Facebook, Messenger, www site content in browser or typed it in any application by user. If a user has pinned a friend as a live tile on their device and the friend posts a particular message on Facebook then the live tile will update and inadvertently cause the device to lock up.
SMS with that string sent to a Windows Phone device will reboot it and the messaging hub will not open despite repeated attempts. If a user sends a Facebook chat message or Windows Live Messenger message to a recipient effect is visible. See how it works here:

Problem exists on any Lumia and it is not device specific but appears to be an issue with Windows Phone kernel, and it can be used to a denial-of-service attack that allows attackers to disable a functionality on a device or even the whole device. There are unconfirmed rumours that the bug in fact is a tool for ACTA and SOPA execution. They have not confirmed this? How extra oridinary! The bug has been reported to Microsoft. And report was not answered even! At this stage, it appears that the only way to fix it is by hard resetting and wiping the whole device, resulting in permanent loss of all user data. As the string that triggers the bug is kept in secret, there is no way for a user to check on his own if problem persists on his own device. It is unknown how many such strings exist which trigger the bug.
The problem was confirmed on devices running the 7740 version of Windows Phone 7.5 while others were on Mango RTM build 7720 devices eg.: http

/mobile.eweek.com/c/a/Security/Windows-Phone-Vulnerable-to-Malicious-SMS-Messages-Facebook-Chats-777208/ (Windows Phone Vulnerable to Malicious SMS Messages, Facebook Chats), According to the bug discoverer, in spite of upgrades, it is still effective on build 8107.
Still want Lumia with WP? It is good phone. Only with some surprises. I need phone security and safety, and also community and devs supporting my needs, not only 3rd party company marketing and incomes, or treating me like an addition to marketing platform. And for this reason I have chosen Linux MeeGo and definitely Nokia N9 for business in my company. And we are safe: from surprises and from malware/viruses thanks to MeeGo linux built-in mechanisms and behavior. I'd like to know what HQ will answer shareholders on questions like: “there is visible and known market and demand for Nokia N9 and MeeGo products and software, so why we do not earn money from this? How our interests and business are in this area? How much money we have from this? What money we will have when users demands more products like Nokia N9? How about demanded tablet with MeeGo? Who is taking care of this and who is responslible?” Could you provide me some simple answers on above questions?
