where do i get full mp3 ringtones for my razr v3r and never get billed? Answered

Remember; the only ways this is 100% ABSOLUTELY COMPLETELY FREE ARE : #1 -- it never shows up on any bill that is made after the download. #2 -- the phone company (in my case, AT&T) never knows about it. #3 -- it says nowhere on the site a message such as "Standard carrier rates apply". i also need to access it from my RAZR's browser.

How would you make a direct link from a phone to an iPod through the TRS jacks to record ringtones? Answered

Hello! This is my first post on this site so I hope it will be a good one! I have both a Samsung Messager and an iPod Touch 4th Gen (I'm not too sure if versions matter in this or not). The phone has a 3.5 mm TRS headphone jack with both three and four conductor capabilities and my iPod has the same. Now, this is the conundrum I am in: My phone has the capabilities to record sound one of two ways, through the built in mic or through the headset (which also has a mic). However, when I do the recording sounds garbled, static-like, and all around horrible. Would there be a way to make a direct link from my iPod to my phone through the TRS jacks? I was thinking that if I did this then the digital sound quality would be much better. Then I could play my iPod, turn on the recording feature on my phone, and easily record the songs as they play. Then I could use those recordings as ringtones. If at all possible I would not like to take apart my phone or iPod but I don't care about the headsets, I have plenty. I have experience in soldering and a bit in cicuitry. Thanks in advance!

How to put Ringback Tones to Phone through Micro SD card?

I recently bought a Micro SD card for my phone (LG Shine II) and have put many MP3's onto it. It gives me the option to use it as a ringtone, but not as a ringback tone. Does AT&T make you purchase ringback tones, and not download them? Any info will be helpful.

Iphone 4S Internal Speaker? Answered

I just purchased an Iphone 4S from verizon 2 days ago, it is the white model. However, the Internal Speaker will not work, and has never worked for anything: Apps, Music, Videos, Ringtones, etc. I made sure the phone was not on silent mode and the volume was up high.  I thought that the headphone detection could be malfunctioning, however when in music, I set the volume to highest possible with no headphones and then plugged in my headphones and the volume bar went to the previous setting with headphones. This makes me assume that it knows to play out of the speakers. Help would be appreciated, if the solution is not fixed, I will be trading in the phone at verizon.

How to use these salvaged cell phone parts?

I found a busted up LG Chocolate the other day (it still turned on but it had no network or anything so I took it) and decided to take it apart and use what I could find. What I got was: -A camera -A microphone -A nice speaker (the loud one that the ringtone plays through) -A little silver circle (what is it!?) -And all of the IC's. I really want to know how I can use the camera, can anyone point me in the right direction? Also, the phone has GPS, but I doubt I'll be able to remove the module without destroying it (especially since I don't know which one it is..) And where is the vibrating motor?!

Amarino: Arduino and Android!

Take a look: "Normally smartphone events are tightly coupled to your phone device itself. When your cell phone is ringing, your phone speaker plays a ringtone. When you get a new text message, your phone displays it on its screen. Wouldn't it be thrilling to make thoses phone events visible somewhere else, on your wearable, in your living room, on your robot, in your office or where ever you want it to occur? Or would you like to use your smartphone sensors, like the accelerometer, light sensor, compass or your touchscreen to control other devices? 'android meets arduino' is a toolkit, basically consisting of an Android application and an Arduino library which will help you to interface with your phone in a new dimension. You can build your own interfaces almost without any programming experience. " I would love to see what kind of instructables come out of these kinds of projects! Amarino
