Hi I've had a t-mobile pulse for nearly a year and a half and lately I keep getting the download unsuccessful message too when trying to download an app, though occasionally the odd one will get through!
I thought that maybe it was my OS that was too old or something, as I haven't upgraded it since I bought it. Not sure what version I have but the firmware is 1.5 if that means anything...(sorry not a techie!). Anyway, could this be part of the problem? Will the newer apps work with older OS's?
I also can't seem to find any caches to clear on my phone, as suggested by people here - are there different types of t-mobile pulses then? I thought there was only two - the pulse and the pulse mini.
I've been thinking of upgrading my phone anyway, but it seems this download unsuccessful is a common problem across android phones? It's making me consider converting to other options such as blackberries (eep!) or even the iphone. But I do like androids so I don't want to have to change systems and lose what I have..
