I feel your pain. I killed my last Blackberry when I dropped it into a Screwdriver(Opps!) back in December. I had to use my spare phone, a Motorola Q9c, and it was horrible. I actually had to use that phone until about a week ago when I got a brand new BB.
Yeah , I know exactly how you feel , on the whole using a spare phone thing .
I actually refuse to use my Motorola Razr in the mean time , which is slowly gathering dust now .
Instead I tell people I won't be able to contact them UNTIL I get my BB back , no matter how long it takes . + Hopefully that won't be too long .....
