[Epic 4G General] ausch30:
This is an old post but the samples that have gone out have an unlocked (S-off) bootloader.

3D has 4GB internal storage. The current GSII has 32GB but that may or may not be the case on the Sprint version, only time will tell. Regardless it should still be more than the 3D's 4GB.

Both come with 2.3.3

3D is a gimmick but I still think it would be cool to play around with. I hate TouchWiz, although I do love the power and control widgets on the notification tray. I actually don't mind Sense and HTC has many more widgets available than Samsung.

It's actually clocked at 1.2 although it's designed to run at 1.5 so there should be some good overclocking kernels available.

The 3D's that are currently out to reviewers and such have an s-off unlocked bootloader.

Someone got one through work. The phone was s-off, he did a system dump and developers are already working on root.

By my count there are 67 custom roms (although several are outdated and no longer in development) for the EVO as well as several development roms.

Here I count 29 for the Epic and I'm sure it's the same deal of many being outdated and/or not fully functional.

The development community for the EVO is outstanding, roughly 3x the size of the Epic. I'm sure the Epic developers are equally as good, there are simply far fewer. Many of the EVO 4G developers, as well as several developers currently on other phones and/or carriers, have stated they're going to the 3D. The 3D development section should be every bit as good if not better than the current EVO section.

Many people, myself included, have had success getting their upgrade date changed.

I do have to admit that Samsung does make some beautiful screens. The one on the 3D will be nice but the GSII screen will be far superior.

1.2GHz dual core, 4x the internal storage, higher resolution screen, larger battery, etc. Both phones are just updates of the previous versions but both phones are more than twice the phone the previous version is.

The version Samsung gave then was a GSM version so it may or may not have any bearing on CyanogenMod coming to the Sprint version of the GSII. Toastcfh has already said he's getting a 3D and will be working with the CM team to develop it for the 3D.

This is probably the biggest factor. My personal opinion is that the EVO got all the developer love because it was released first, about a week or so before the Epic was even announced. This year seems to be a repeat as the 3D will come out in about a week and there's no official word on whether Sprint will even get a version of the GSII.

I had a EVO from launch day until yesterday. I encouraged a friend to buy the Epic when it was released and I've been doing tech support/Android tutorial on it ever since. I decided that since I'm upgrading I'd give her my EVO and take her Epic until the 3D is released. My 3D is already pre-ordered and I can't wait. The hardware in the Epic is superior to the EVO (although I don't care for the smaller screen). The build quality seems comparable but, in my opinion, the EVO just has a better feel to it. The developers are what really makes the EVO 4G great. There are several AOSP roms to choose from. Sense roms with Sense 1, 2, 3 or combinations of them. Both will be great devices but the great expience with the EVO and the EVO development community is all I need to convince me the 3D is going to be my next phone.
