Anyone familiar with Google Voice knows that's not a fair assessment. The apps provided a completely different spin on said features (the phone dialer, text messaging and others) through the Google Voice service, which allows you to create and use a virtual phone number of your choosing, chock full of unusual extras not currently possible on most cell phones or land lines.
Those features include the ability to listen in on voicemails as they're being recorded, digital transcription of voicemails and calls, and assigning different rules or voice greetings to different contacts.
Sean Kovacs, developer of GV Mobile + [iTunes link] assured everyone on Twitter that the app is coming (it hasn't appeared just yet), and promised to make it free for the night if it starts trending.
Like GV Connect, GV Mobile + is priced at $2.99 and supports transcription and playback of voicemails, call initiation using your Google Voice number and most other features features you're looking for or have been using for a while if you have a jailbroken iPhone or an Android device.
If Apple has really changed its policy on this, don't be surprised if you see a lot more of these coming.
