$9.99 deal on extended battery for smartphone from Richardsolo.com
There's a deal going on at Richardsolo.com for an extended battery for smartphones including using it for your blackberry for $9.99 I have one of these and it works well, slowly, but is handy to have just in case your 9900/9930 goes dead. Below is the link if you want to check it out. You can even use the retractable USB cable for your playbook. For US residents only I guess no longer available to Canadians :(
