I've been complaining for some time about the horrible memory problems on the Blackberry Bold. I've been running most of the same applications on the 9000 as I did on the 8800 and it's clear that there's a massive memory leak.
Not only that, but the battery life has been abysmal compared to the the 8800.
Well.... no more.
Blackberry have released a patch for the Bold which updates the firmware to 188.8.131.525
I've been running for several weeks on this patch and haven't had to reboot once since applying it. The battery life is back up to the 3+ days I've come to expect from the Blackberry too.
