Relatively knee-jerk reactions to my new iPhone 3GS compared to my old, original iPhone after roughly 39 hours of ownership
My new iPhone is much faster. Every function performs better, from finding wifi to launching apps.
The iPhone 3GS feels noticeably lighter than the first-gen phone, despite their officially weighing the same in grams.
According to my wife, people calling my phone can now hear me clearly, as opposed to my old one, which had developed awful reception and sound quality. On my end calls are less crunchy but not entirely different.
The warmer white point makes everything look irresponsibly yellow. I feel like my phone is jaundiced.
The ringer/vibrate button is in higher relief than on the old phone, and every time I put it in my pocket, the ringer turns back on. I hope my soon-to-arrive case will mitigate this effect. (Also: the AT&T Wireless store charged me $10 more than the manufacturer's website pricing for the aforementioned case. Rude.)
I am now keeping up with the joneses... until July, when the iPhone 3GT or whatever makes me instantly out of date.
