G1 comes with an adapter for normal head phones.
iphone had to BUY an adapter.
-Seriously, with the G1 battery life, you shouldnt even listen to music on it, and really no one listens to music much on their phone, cause everyone owns an ipod
G1 can put wallpaper on home screen.
iphone had to jailbreak it to put wallpaper on it.
-you can change the unlock screen, but im pretty sure that if you have a picture on your background=more battery consumption, thats what i heard (something about more pixels)but this isnt even a big deal
G1 can put useful apps on it without jailbreaking.
iphone have to painstaking jailbreak for apps are wallpaper, themes or farts.
-There arent even many apps on the G1, all the apps there are iphone app clones or watered down versions, plus there are plenty of apps on the iphone that are useful
G1 has real key board with real keys.
iphone virtual keyboard, keep mistyping letters and have to delete a lot of times.
Keyboard added thickness, almost twice as thick as the iphone
not worth the trade off for me, also if you want to type something or text, you will have to open up the keyboard every single time, no virtual keyboard
G1 removable memory so it unlimited.
iphone non removable so once it is filled up that's it.
G1 changeable battery, one goes dead pop in new one.
iphone dead battery that's it, done until you find a charger.
a non-removable battery = more battery life
i can use my 3g iphone as much as 4 days at most, while having the g1, the longest i went was 17 hours ish (thats with wifi, 3g, gps off) I hear people even carrying 2 battery packs with them, or even buying an extended battery for their g1, bringing the phone to an inch thick
you wont even have to keep charging your iphone as much, g1 you are going to have to constantly change battery packs with heavy usage, and its a pain to take off the battery cover, some people even break it, its also a danger to accidentally hurt the screen since its only held onto those hinges or whatever
G1 put great 3rd party apps on sd card easily with pc
iphone if it is not in app store or cydia it does not go on phone.
iphone already has great 3rd party apps, most likely if theres an app for the g1, its going to be on the iphone, if its not already on the iphone
G1 real useful phone.
iphone toy
Both are useful phones, iphone is more multimedia friendly
but at the end of the day, G1 is dead cause the batteries died
