Hello, I am a new HTC Hero user. This is my first smart phone. Previous to this I only used my cell phone to talk on, nothing else. This is a overwhelming new experience for me. I would like to set my phone up for maximum speed when using GPS and surfing the internet. If anyone has any suggestions or apps that would help that would be great. I will be doing some texting, is there a way to add a signature to the text? Again, thanks for any info and I will look forward to exploring this new source for android info.
