Just started using my Desire last night! Feeling good. However... Was just on a call, tried to use the Android Marketplace. Couldn't. Got curious, and tried to use Google Maps mid call. Couldn't. Tried to use the internet during the call. Couldn't. Now, I'm on T-Mobile (UK) and have just come from a Nokia E71. With my E71 I could make a call and use Google Maps. Am I missing something or is this bit of multitasking somehow not possible??? Please tell me I'm missing something!
