Nokia :: How Do I Answer Calls - Key Guard Slide Switch Is Broken?

I've mentioned this on another thread, but I thought I'd start a new one to see if anyone can help me with this specific problem. Briefly, the familiar tale. Phone well cared for and never dropped, keyguard slide broke off after six months, Carphone Warehouse said it was a 'cosmetic' fault and therefore not covered under the warranty and wanted £85 to repair it. nUnlock application downloaded, which resolves most issues other than answering calls. Many of us have been there. The big niggle that remains (other than the prospect of having to give in and fork out for a repair I shouldn't have to pay for) is answering calls. This is the current scenario: Phone rings. I can't answer it in the normal way due to the keyguard switch no longer being there. So I have to flip it open, at which point the screen goes blank for a couple of seconds before it comes back on in the 'sideways' configuration. In most cases, by the time the screen has come back on and I've hit the Answer key, it's gone to voicemail. It's fiddly and annoying. So. Have I missed something in the nUnlock app that disables the keyguard switch function altogether so I can answer calls properly? Is there something in the Phone Settings that I've missed that does the same thing? Or am I just going to have to go to a Nokia shop and be prepared to argue and/or fork out some cash?
