My elder sister told me the same thing but its not true @ all. I use my blackberry to apply for all jobs except ones whose website were designed in such a way that only a system can open it, and I've bin called for so many tests through them. That was even the major reason why i got this phone because i know it won't be convinient for me to be going to the cyber cafe all the time.
What ill advice you to do is to remodify your cv in such a way that u can't be overlooked when u apply for a job.
