[G1 Apps and Games] Klyentel:
Not sure if you all are familiar with this app, I haven't seen anyone speak upon it on XDA yet, so just thought I'd share my experience with it.:)

IMO, this app is pretty cool. Very simple and easy to use, although it doesn't come with detailed instructions on how to use, so I felt the need to explain a little bit about it:

Tired of lags to and from Dialer/Contacts/Call Log?

Have you ever pressed the call button to dial a number/contact and nothing happens for 10 to 15 seconds then finally the call goes through and starts to ring?

Ever went back to home screen after fooling around with an app, or web surfing the browser only to find that a widget or two is missing or is not loading/refreshing properly?

Gmail not syncing daily as it usually does?

Market taking forever to load up the downloads page or lagging connection with G-talk to promptly start the download/updates you started?

Well these are the memory/background/content provider situations that need to stay snappy if nothing else does, agree?

Then this app may or may not be the answer to all of your problems.

For me it was. First and foremost, it is a FREE app, yay! (at least to my current knowledge, unless developer has changed it)

*FYI* This app does require root permissions, so if you are not rooted this will be of no use to you.

After installing, when first opening the app, super permissions should pop up, just check the always box and press allow for root access. Close the app, then re-open.

Now, there are 4 options you may choose, DEFAULT< CUSTOM< MILD< AGGRESSIVE

Default

settings will be what you see on first use, those are the default Android memory settings for your G1

Custom

- self explanatory, you move the bars of each memory category according to how you prefer- *Note* the amount shown is not exact memory, it is a threshold, basically a set amount not to exceed, Your phone will automatically choose how much to use according to how much it needs, but its limitations will be set by the threshold you choose. Go ahead and make your adjustments, then click the custom button, this will save these settings. So the next time you want to re-enter those settings, just hit the custom button, and it will restore.

Mild

- Simply a preset application setting

Aggressive

- Another preset app setting

You choose what works best for you, I would suggest playing around with different settings until you have achieved a memory usage that gives you the most improvement, *Note* Do note mistake this as a speed app, it only controls memory, so don't expect some super fast change, but if you set it up properly, and memory is being managed to the best case scenario of your usage, speed will increase, believe me.

Start with the presets, see how they work throughout the day, if you notice no difference, or worst than it already was, change it to something else.

Personally, my best experience has been with the Aggressive preset. Its been the most effective for my phone, however; this won't be the case for everyone. Aggressive basically raises the threshold for background data(widgets,home, cache, etc.) And content provider (google apps, settings, G-talk and stuff) And Empty application- this means, IMO, the amount of free memory sitting around available, for soon to come data or apps that you might open later, I.E.- multi-tasking, Call screen, new mms or sms

It also lowers the threshold of the foreground and running apps, so that they don't suck up so much memory the phone lags before it can open other things in memory. Get it? But as I stated, different people will have different preferences.

If you haven't already, try it out! If you don't like it, or don't need it...maybe results won't change things enough for you to have any use for it, you can always uninstall, and it won't harm any memory or data on your phone.

Also, regardless of threshold settings, if you open or use more memory than threshold limits, it will not break or crash you phone causing reboots or anything like that. So don't worry. The app does not prevent you from doing anything on your phone, it simply manages it according to your use.

I hope this comes in handy for someone, as it has been more than useful for me on a daily basis. You can find more information via market or the link above.
