The Infuse is 400mhz faster then the iphone 4. not much but over time the infuse wont get as slow. dont get me wrong, both phones will be highly usable for 2 years and wont slow down much. The infuse 4G has an 8mp camera and the iphone 4 has 5mp. 5mp takes brighter pictures and has a little better low light pictures. Though MOST people prefer the 8mp. they both record HD 720p videos. the infuse has ALLOT bigger screen. which is great but the infuse sceen is noticable less clear than i phone 4. The infuse is still considered a high resolution screen and very clear. but iphone is clearer. The iphonee 4 will have ios 5 and the infuse will have android 2.3 gingerbread. but will be updates to 4.0 in 2012 sometime. the infuse 4g is thinner than iphone. The iphone 4 is slowwwwww 3g and the Infuse 4G is very high speed 4G. The infuse has bluetooth 3.0 and the iphone 4 has bluetooth 2.1.
I prefer the Infuse WAY more because its faster bigger FASTER and has more customization. even though u will have to wait a while for android 4.0, its allot better then ios 5. look up android 4.0 on youtube.
The Galaxy Nexus will be coming out to verizon in November 2011 and will come out for At&t probably in December but possible January or February. The Galaxy nexus is the best and fastest phone in the world. Android 4.0 makes it the fastest. Look up Galaxy nexus on youtube. it is twice as fast as the Infuse and three times as fast as the iphone 4. it will be 4G and have a 4.65 inch screen which is as clear as the iphone screen. but the nexus has better and brighter colors. deeper blacks and brighter whites.
