BlackBerry vs iPhone: Which is Reliable?

As per a study conducted by Square Trade, a mobile phone warranty firm, BlackBerry cellphones had twice the malfunction rate than the iPhone in the first year use. Square Trade had released a study of 15,000 individual handsets covered under the company's policies.

From the study, it was found that Treo had the worst failure rate of 16.2 per cent in the first 12 months of usage. BlackBerry phones showed up 11.9 per cent failure rate while iPhone's malfunction rate was 5.6 per cent. Canalys research report mentioned that Apple cruised ahead of RIM.
Apple's iPhone reported majority of problems with touchscreen and battery. Even the glossy and smooth outer made it difficult to handle and slip out. Battery issues of around 1 percent reported for BlackBerry and Treo compared to half percent of iPhone. To be noted, SquareTrade's study didn't have software issues fixed by firmware updates under their scanner.

SquareTrade projected that iPhone's failure rate might become nine to 11 percent in next two years, which are estimated figures since the phone hasn't been there for long. While Blackberry and Treo hand sets got projected failure rate of 14.3 percent and 21 percent respective.
