[Touch Diamond, MDA Compact IV ROM Development] Kirkaiya:
1.37.707 (Asia) comparison to 1.37.456 (ME)

Okay, this is my "1 full day of use" comparison.

I originally got my Diamond about two weeks ago (from a mall in Bangkok, near where I live). It came with rom 1.35.xxx, which I already knew (from reading xda-developers :) ) that I would upgrade.

So for almost two weeks, I was using

RUU_Diamond_HTC_Asia_WWE 1.37.707.1

After flashing that, I also upgraded to .NET CF 3.5, installed to main memory (not the 4GB internal storage).

With this setup, TF3D was quite smooth, with no noticeable lag. There was a sometimes annoying lag when tapping an SMS in touchflo and waiting for the WM6 messaging/outlook app to start, especially if it wasn't running already. There was also a slight memory-leak problem, but a soft-reset every other day seemed to be a solution for that.

As a data device, though, it was pretty good. Where it fell down was as a phone. The "answer" interface was sometimes *incredibly* slow to appear, especially if I was using Opera at the time (so bad that some calls went to voice-mail before I was able to answer them...)

The soft "Answer" button on the screen only worked sporadically, and sometimes I ended up mashing the hard-button "answer" so many times, trying to answer the call, that it ended up on speaker (i am not sure why).

24 hours ago (and I've been awake for all but 4 of them) I flashed:

RUU_Diamond_HTC_WWE-ME_1.37.456.2

I also upgraded this to .Net CF 3.5 (again to main memory). In addition, I restored all my emails, sms and personal settings using Sprite Backup/Restore (which I downloaded from HTC Club, along with the ROM).

After heavy usage for much of the 20 hours I was awake, things I know for sure are:

TF3D performance is roughly the same as .707 Asia ROM. It's still smooth, fast, and responsive.

There is noticeably less lag when moving from Touchflo into a WM6 application. Clicking "inbox" from the email preview tab, or clicking "reply" to an sms is snappier. Not Earth-shatteringly faster, but more responsive.

The phone functions are FINALLY usable!!! The answer-screen comes up immediately, and the soft-button works now. Even the note-taking app quickly comes up during a call. For the first time, I was able to smoothly switch between two calls (when receiving a second call while already on one).

Things that I don't know, but think might be true: the memory leak seems less. I have had most major apps (including Opera, Contacts, Calendar, Messaging - email and sms, Google Maps, Teeter, OneNote, Camera, Photo Album and Total Commander) open at least once, most of them multiple times.

The drop-down task-list says I'm using 69% of memory, with ActiveSync, Contacts and SMS/MMS apps open right now.

This seems better than I had before.

Battery life also seems better (I just plugged it in, but I don't think I was going anywhere near 20 hours before without a recharge, but I didn't make a lot of voice-calls, so I don't have any solid data to back this up.

Anyway - overall, I think it's a winner if only because the phone functions finally work as I expect. I have done no ROM tweaks yet (on the .707, my only tweak was to enable wake-up on sms, which I will do for this rom also).

So anyway - if you're using the 1.37.707, and live in Asia, you can definitely download the ME 1.37.456, and it's definitely an improvement in some areas, and works fine with DTAC (my local mobile network provider).
