Wow...a lot of conflicting stuff here. I know most of this thread is over a month old, but since it's now active again and others searching may find it...
1. It is VERY possible to do group messages with iPhone users. You have to ensure that group messaging is turned on in the messages app, but that's about it. The messages will be sent as standard MMS messages, and those using iMessage on iPhones will still get the message the same way they did before, but your text will now appear in a green bubble instead of a blue one (or vice versa, I can't remember), but it WILL be a group thread. You will lose some iMessage features and be a lot more restricted to message size (photo attachments, video, etc), since MMS has a
much smaller file size limit than iMessage, but as far as actual group texting capability, MMS can handle that.
2. If you are a current iPhone user, but sure to remove your phone number from the iMessage app before switching to Android; otherwise you may have some issues texting with other iPhone users. I'm not exactly sure how to do this, but there are plenty of threads with detailed instructions
3. While they may work just fine, the problem with using 3rd party chat clients is that it requires effort on the receiving party/parties to install and set them up, so they're not always a viable alternative. What is great about iMessage (if you're an iPhone owner) is that it's completely integrated with the SMS interface, so you don't have to have your friends set anything up on their end.
To add to the above point, Google Hangouts (formerly Google talk) is getting there...it's a great app with features for group messages, media sending and video, and pretty much everyone that owns an Android already has a Google Account and access to the app...plus it can be accessed from a desktop. The only thing really missing is SMS integration, though Google has stated that feature will be available eventually. The other great thing is that Google Hangouts is available for use by iPhone users -- yes, it does require them to install it -- but given that iMessage isn't available to Android users
at all, I think this is an advantage to the Hangouts platform. I've converted many of my friends over to Google Hangouts (both Android and iPhone users), and everyone I know who uses it really likes it.
Do you have to initiate the group message? what if the iphone user initiate the group message would it still work? thanks
Yes, it should work just fine...I group message with iPhone users all the time, it doesn't matter who
starts the message.
