RIM has claimed that the launch of their new smartphone Blackberry Storm has been normal and as per expectations.

But the mobile phone suffered from problematic software which is being fixed by the company.

Market sources tells us that the company only managed to sell just half a million of this touchscreen Blackberry model in the final weeks of last year.

This is pretty small number compared to the iPhone units Apple sold in the same period.

RIM co-CEO Jim Ballsillie said in a statement that the company is manufacturing about 250,000 Storms per week. He also admitted that the phone shipped with buggy software but that is to be expected from the new generation phones which are much more complicated compared to previous generation phones.
