N73 Repair centre? I broke my phone

[schnozzles]

Hi all

i didn't take out insurance when I upgraded my phone last month as i thought we had accidental damage cover included in our contents insurance - it turns out that we don't and so my phone probably isn't covered... and unfortunately it got knocked into a cup of tea last night. A cup of tea which had sugar in!

The screen isn't looking too great and none of the keys work, but the phone powers up.

So... is it worth me investing in a T6 screwdriver and attempting to clean it out myself? Or should I send it off somewhere? And if so, where's the best place to send it, can you recommend somewhere? I'm in Leicestershire, UK.
