congrats on your purchase, its an amazing device. i recently ditched my iphone 3gs in favor of the n1. i have no regrets. one thing i will say is that you may notice the screen is not nearly as responsive as the iphone and the ui is not as fluent (scrolling for example). however once you adjust to that the phone is great, blazingly fast, blows my 3gs out of the water and that phone was no slouch. word of caution, since the platform is so open and not limited like the iphone, watch your battery usage closely, as it does tend to die alot faster than the iphone, then again theres alot more going on within the os compared to the iphone (i.e backround processes). these are just my experiences coming from the iphone, others may have various opinions. i have found call quality to be excellent and while i may not have as many bars of signal as i did with the iphone, the connection is still great and havent experienced any loss of signal or dropped calls. overall, phone is great, hope you stick around and enjoy it
