I have a Blackberry Pearl. For some reason,I can't load up the software on my computer, to use the BB with the USB port. So, I'm having to download the aps, into my BB. The Twitter ap, Twitterberry freezes my phone every time I use it. I have Window's Vista, and neither the USB cord, nor the software, either from the CD, or from the website, works. is there a Twitter ap that will not freeze my BB?
