As an old Nokia wizard I used to walk & type with one hand, I have tried this with the Pearl and it doesn't work. It is not possible to type 0-9 or any of the punctuation marks that can only be reached with the shift key (!?@.,+*)
Or does anyone have a solution (other than using my other hand!).
Seems like a minor irritant that could be solved by RIM quite easily (press the letter key long enough to get the number, include !?@.,+* in the symbol menu...
